  • Hi syamkrishnan,

    What type of application you are development, Winforms, WPF, asp.net, or others, is it a C# application? could you please share related code, detailed error message, the steps about how to reproduce the issue.

    Best regards,

  • Probably the remote host does not accept .xls files and dropped the connection when it see the file name is .xlsx.

    If that's the case you'll need to contact remote site owner to also accept it, or see if they accept file in other form such as zipped files. (Of course if the remote side will need to do further processing with file, it'd be more complicated)
